Back in January, I described our plans to stage a side-by-side sensory analysis of Castillo and Caturra samples grown by participants in our Borderlands Coffee Project in Colombia. Originally, we had planned to do this exercise independently. But as we moved forward in our planning and began talking to more and more friends in coffee about what we were doing, we realized that the study–both the methodology and the results–have broad relevance for the entire coffee sector. We invited World Coffee Research to partner with us to help make the approach more rigorous and the results more robust, and we were delighted when WCR accepted.
The collaboration, now known as the Colombia Sensory Trial, will revolve around two panels at the Intelligentsia Coffee lab in Chicago, the first in October and the second in January 2014. (Thanks, Intelli!)
Paul Songer of the Alliance for Coffee Excellence will lead the process. Confirmed panelists include:
- Aleco Chigounis, Red Fox Coffee Merchants
- Tim Hill, Counter Culture Coffee
- George Howell, George Howell Coffee
- Doug Langworthy, Starbucks Coffee
- Adam McClellan, Stumptown Coffee
- Geoff Watts, Intelligentsia Coffee and
- a-cupper-to-be-named-later, Keurig Green Mountain

Hi Michael, how do you plan to control for environmental conditions (soil, shade, etc.) and management practices, the beneficio in particular? I’d also be interested on knowing if you’ve looked into how theFederatipn went about testing cup quality in developing Castillo, perhaps using that as a benchmark for designing your experiment
I guess I should have read the press release first…
I’m still interested in the Federation angle though. What about asking one of their cuppers to participate? It would broaden the discussion by bringing their criteria into dialog with what the folks you’ve invited invoke. While quality isn’t merely in the mouth of the imbiber neither is it wholly objective. It’s a judgement call and it seems like it would be fair to bring the Federation’s decision making/makers into the conversation.
I think that could be unfair to the FNC cupper – a no-win scenario. If s/he rates Castillo consistently high, would it mean a bias? If low, they would get it in the neck from FNC. Even though anonymous, these things leak out?
Turns out the FNC is sending someone to participate in the panel–a fantastic development from my perspective. We will do our best to see he doesn’t get it in the neck!
Thanks for your comment(s) here.
The design is the product of a collborative process involving CRS, CIAT and WCR. We think the independence of the process is an important source of the Trial’s value.
The cupping panel is another story, however. The Federation is welcome to join. We are holding a seat at the table for one of its cuppers!
Hello and sorry for the long delay in getting back to you. I am happy to report that the Federation is, indeed, sending a cupper to the panels in Chicago. I am delighted by this news and think, as you point out, it is wholly appropriate that the Federation have a seat at the table given how much it and its related institutions (Cenicafé which developed Castillo, the banks that have financed the massive wave of renovation with Castillo, etc.) have invested in this particular hybrid.
Very interesting, and curious about the results. But why only US focussed? Absolutely no offense to all pro’s and their companies, but they are all “country-specificity” regarding location, origin, “environmental peculiarities” (temperature, humidity etc). In other words, to have a real worldwide and complete view on this subject pro’s like Norway’s Tim Wendelboe, this year’s World Cuptaster Champion from Taiwan, UK’s John Thompson (COE judge), a pro from Australia and Africa should be included? (And perhaps me too ;-))
Thank you for your email and your very fair critique.
No U.S. conspiracy here, just evolved this way. As I mentioned in the post, we originally began designing this process for the six members of the Borderlands Coffee Project Advisory Council: Atlas, Counter Culture, Intelligentsia, Keurig Green Mountain, Stumptown and Sustainable Harvest. Four of them opted into the panel, and WCR helped us bring Aleco/Red Fox, Doug/Starbucks and George Howell into the process to round out the panel. (We are, as I mentioned to Chris in response to his comment, holding the 8th and final panel seat for a cupper from Colombia’s Federación Nacional de Cafeteros.
We are, however, making smaller flights of sample pairs available to select roasters for lab-based cupping. If Tim Wendelboe wants some, we’ll send him some!
Just wanted to give you a little update on the issue you raise here of participation in this cupping process. While the two panels that will form the basis of the Colombia Sensory Trial were already fixed by the time this post was published, we have managed to squeeze two non-U.S. roasters onto the list of lucky companies that will receive a smaller flight of sample pairs from the study. Thanks for the gentle nudge, and stay tuned to the Coffeelands blog for results from these roaster-based cuppings beginning later this year.
I’m really looking forward to the results of this study.
One query, would it be possible to convert scores to a rough estimation of sale price ($/lb)? We are trying to develop decision tools for farmers, so we need some idea of level of penalty if Catimors are indeed of inferior quality. It would be really interesting to see how this might vary with altitude for instance.
Thanks for your comments. Always good to hear from you.
Thanks, too, for your excitement about this project. We can hardly wait to get started at the cupping table.
You (naturally) raise the most important question. The issue of sale price really more important from our perspective than the cupping scores–it’s the “so, what?” of the cupping scores for the grower.
I wrote about this issue at some length here and discussed it again in this interview with Daily Coffee News. A grower won’t be swayed by a clear correlation bewteen genetics and high cupping scores unless she has a ready buyer for that higher-quality coffee that is willing to pay her a good price for it. If not, quality is weighted less in the decision-making process, and productivity, resistance, density, etc. are weighted more. So, agreed on the importance of price.
As far as estimating sale prices, I think the exercise is manageable. In my mind, the baseline price is probably a weighted average of three price points on the day we collect the dried parchment from the farm: the Colombia internal price, the price being paid by Carcafé for Starbucks C.A.F.E. Practices verified coffee and the price the Federation is paying for Nespresso AAA coffee. Almost all Nariño’s coffee is sold at one of these three price points, so an average in which each data point is weighted according to the approximate market share of each should reflect a reasonable estimate of the value of the “losing” coffee from the sensory trial.
If, as you suggest, “Catimors are indeed of inferior quality,” we could construct an “estimated penalty” by polling panelists on what they might be willing to pay for the higher-performing coffees, averaging out those estimates, and subtracting the baseline price from that amount to determine the “Catimor penalty” or the “Caturra premium.”
This would be a factor that would feed cleanly into the decision-support process you mentioned. Weighing the “Caturra quality premium” with a clear understanding of the “Caturra productivity penalty” we could provide some interesting feedback to growers on expected ROI for the variety.
Then there is that pesky question of the market.
As a kid, I used to collect baseball cards. I bought a price guide to track the performance of my investments. Once when I got excited to see how much one of my prized cards was “worth,” my Dad wisely explained that something is only worth what someone else is willing to pay for it.
In other words, the Caturra quality premium is just a number on a piece of paper until a grower finds a buyer willing to pay her that much.
PS: You ask about elevation. We have stratified the farms into three elevation tiers:<1650 m (low elevation in Nariño), 1650-2100 m and >2100 m precisely in the hope of better understanding the interaction between genetics and elevation.
As always, getting right to the nub of it–how do the cupping scores on the table translate into farmgate prices for growers? Indeed, that is the real question here. Tim Schilling, who is by my lights such a wonderful scientist precisely because he, like you, always sees to understand the application of his science to the lived realities of people, summarized the research this way: “Farmers need to know what variety is going to give them the best bang for the buck.”
I know I responded to this question already (and wrote about it at some length here), but as I reflect on it further there is a problem with the exercise of “estimated prices.” I know we could go around the table at the panel and get roasters to tell us what they would generally pay for a particular coffee based on its quality tier, A, AA, AAA, microlot, etc. The question isn’t WHAT IS THE COFFEE WORTH, but WHAT CAN THE GROWER REALISTICALLY EARN for that coffee. The truth is that in Nariño today there are MANY growers capable of growing AAA-grade coffees that would–in theory–qualify for quality premiums from the kinds of buyers willing to pay them. There are significantly fewer, however, who have any way to get their coffees to buyers like that.
We will keep this present in our analysis as we review the results and draft the final report early next year.
